Answer:

-6 > x

Step-by-step explanation:

3 (x-6) +2 ≥ 5x - 4

3x-18 + 2 > 5x - 4

3x - 18 > 5x - 6

-18 > 2x - 6

-12 > 2x

-6 > x

Answer:

x ≤ -6

Step-by-step explanation:

Distribute 3 through the paraentheses:

3(x - 6) + 2 ≥ 5x - 4

↓

3x - 18 + 2 ≥ 5x - 4

Calculate the sum:

3x - 18 + 2 ≥ 5x - 4

↓

3x - 16 ≥ 5x - 4

Move the variable (5x) to the left-hand side and change its sign:

3x - 16 ≥ 5x - 4

↓

3x -5x - 16 ≥ - 4

Move the constant (- 16) to the right-hand side and change its sign:

3x -5x - 16 ≥ - 4

↓

3x - 5x ≥ - 4 + 16

Collect like terms (3x and - 5x):

3x - 5x ≥ - 4 + 16

↓

-2x ≥ - 4 + 16

Calculate the sum:

-2x ≥ - 4 + 16

↓

-2x ≥ 12

Divide both sides of the inequality by -2 and flip the inequality sign:

x ≤ -6

Which expression is equivalent to square root 55x^7 y^6/11x^11 y^8? Assume x > 0 and y > 0.

morpeh [17]

The first step for solving this expression is to reduce the fraction with 11.
$\sqrt{ \frac{5 x^{7} y^{6} }{ x^{11} y^{8} } }$
Now reduce the fraction with $x^{7}$ .
$\sqrt{ \frac{5 y^{6} }{ x^{4} y^{8} } }$
Reduce the fraction one more time with $y^{6}$ .
$\sqrt{ \frac{5}{ x^{4} y^{2} } }$
To take the root of a fraction,, we must take the root of the numerator and denominator separately. This rule will change the expression to the following:
$\frac{ \sqrt{5} }{ x^{2} y}$
Since we cannot simplify this fraction any further,, the final answer is going to be $\frac{ \sqrt{5} }{ x^{2} y}$ .
Let me know if you have any further questions.

Find the perimeter of the rectangle? Needs to be in standard form

vladimir2022 [97]

Answer:

6b - 4a + 22 units

Step-by-step explanation:

Perimeter = 2(length + width)

= 2(3b - 4a + 5 + 6 + 2a)

= 2(3b - 2a + 11)

= 6b - 4a + 22 units

- Which fractions are equivalent to 6/8?

natima [27]

Answer:

3/4,

12/16,

18/24,

24/32

30/40

...So on, So on...

Step-by-step explanation:

Any fraction that you multiply by the same number on the bottom and on top.

So, multiply by two, what you do to the top do to the bottom. = 12/16

Multiply by three = 18/24

So on, so on.

Or you can reduce, 6/8 divide by 2 = 3/4.

I'm gonna give you 5 equivalent equations. I also taught you how to do it!
